To be honest, I'm hoping they'll just let him be, though. It's kind of like Louisoix... if we were to in the future learn via echo that some currently alive and important character had dealings with them that we never knew about, that would be an ermahgerds moment... but I think there's more to be preserved by leaving it alone than there is to be gained by going back for more.

This is entirely different reasoning than Lou, however. In his case it was all about the sacrifice; in this case it's all about the ambiguity. There's just enough to get a good view of who he might have been and why he might have acted, and I think we all have a slightly different view of it. Going back to answer too many unanswered questions might change the whole meaning he has to some of us, or even make us like him less.

I just hope they tread carefully and don't burn him out. He was a great villain.
